         <p class="style1"><span style="FONT-FAMILY: Arial; FONT-WEIGHT: bold">Model M107/M607x modular Transmitter</span><span style="FONT-FAMILY: Arial"> is a new product developed byShanghai Qianjin Electronics Equipment Co., Ltd. It consists of M107 (Intelligent Chassis), and M607x Transmitter Module. The Appearance of the chassis features LCD display, thin film switch, finger-mark-free steel plate, and a vivid color, which make the unit look elegant and modern. </span></p>
         <p class="style1"><span style="FONT-FAMILY: Arial">M107 is a one intelligent standard 19" 1RU chassis. M107 can be monitored by the network management software, even though there is no transmitter module plugged into the chassis. In this way, the network management software can get clear status of the available slots in all intelligent chassis, M107. Except for M607 (Optical Transmitter Module), the other modules such as forward optical receiver, reverse optical receiver, and etc., can be plugged into M107, which offers two respectively independent slots. </span></p>
         <p class="style1"><span style="FONT-FAMILY: Arial">M607x optical transmitter module has 4 kinds of specification classes, and each class has totally 11 output powers including 2，4，6，8，10，12，13，14，16，18 and 20dBm, . (Refer to the Ordering Information below) M607x optical transmitter module uses an internal isolated Distributed Feedback (DFB) laser, which represents the latest technology. Its high cost-effective and wonderful performance are highlighted by its advanced multipoint pre-distortion correction circuit, RF pre-amplifier circuit, high reliability of power supply, intelligent and efficient element management, and unique air- flow design.</span></p>
